Whistlejacket: The Horse Portrait That Broke the Rules

August 2025

A horse, life-size, rearing against an empty golden background. No rider, no saddle, no landscape. In 1762, George Stubbs painted Whistlejacket, and it is still probably the most famous portrait of a horse ever made.

A racehorse and a rich man

Whistlejacket was an Arabian chestnut stallion. In August 1759, aged ten, he won a famous race at York, his last before retiring to stud.1

He belonged to the 2nd Marquess of Rockingham, one of the richest men in England and briefly Prime Minister, whose passions were classical sculpture, racehorses and gambling. Rockingham commissioned a life-size portrait of his prize horse, on a scale usually reserved for group portraits or history paintings.1

Eighteen months with horses

Stubbs, born in Liverpool on 24 August 1724, the son of a tanner, was largely self-taught.2 In the 1750s he spent 18 months in a remote Lincolnshire village dissecting horses, in a barn fitted to hang the carcasses from the ceiling, drawing every stage.1, 2

The result, The Anatomy of the Horse, published in 1766, became a major reference for naturalists and artists alike.2 No British painter of his day understood a horse's body better.1

The rules it broke

Compare Whistlejacket with a more usual Stubbs, like the Met's hunter above: a groom, a dog, a landscape. In Whistlejacket, Stubbs leaves out any rider, riding equipment or location, and paints the horse against a neutral background of pale gold.1

The rearing pose, called a levade, had been used by Rubens and Velázquez for heroic portraits of kings on horseback. There, the horse is always under the rider's control. Here, there is nobody to control it.1

Stubbs also took liberties with anatomy for drama: you can see the rump and the forehead at the same time, and both the right knee and the underside of a hoof.1

“The riderless horse is the embodiment of unrestrained natural energy.”

Was a king meant to ride it?

A story claims that a rider, perhaps George III, was planned and then dropped. The National Gallery finds no evidence: Whistlejacket's back is too short for a saddle, and the canvas shows no drawing of a rider. Viewers were simply unused to the idea of a horse portrayed on its own.1

That freedom is why the gallery sees in it a spirit that prefigures Romanticism's celebration of nature,1 the mood we met in Friedrich's Wanderer. For horses painted in a very different spirit, see Franz Marc's blue horses.

A horse on the wall

Stubbs proved that one animal on a plain background can hold a whole wall. A horse portrait works best with room around it, on a calm wall, in a hallway, a library or a boot room.

Choose a vertical canvas for a rearing or standing horse, a horizontal one for a gallop.
